Opportunistic spectrum access (OSA) in a decentralized network is a challenging problem since each unlicensed user (i.e. cognitive radio (CR)) needs to characterize frequency bands as per the occupancy statistics of multiple ...

Material properties of wide-bandgap semiconductors are excellent candidates to build highly-efficient and highly-linear power amplifiers required to support cellular communication. AlGaN/GaN HEMTs are considered the most ...

Branch-line coupler and phase shifter are widely used passive components in RF and microwave communication systems. The designing of circuits operating at multi-band frequencies has the advantage of both compact size and ...

To support wide variety of services ranging from voice, high-speed data and multimedia, multi-standard wireless communication transceivers (MWCT) are desired. Such transceivers have the capability to adapt to any desired ...

Non Volatile Memories (NVM’s) are an integral part of every System-on-Chip (SoC) for retaining the data when power goes off. Phase change memory (PCM) is type of NVM and exhibits significant advantages over existing NVM ...

A new vernier delay line time to digital converter (TDC) architecture using a tristate buffer is proposed in my thesis work. The design being implemented in this thesis work is a single stage vernier delay line time to ...

Most modern circuit designs have a mix of analog and digital circuit blocks integrated on a single chip. Such designs require a dedicated power man- agement unit to provide a stable, regulated and clean power supply. This ...

Audio applications necessitate precise data conversion from analog to digital domain. This high resolution conversion can be achieved by using Sigma-Delta architecture, which operates at oversampling rate and exhibits ...

Moving towards deep-submicron technologies, packaging density of ICs is increasing and thus the number of storage elements is also increasing on an IC. Any data corruption in these storage elements leads to huge amount of ...

Power conditioning circuits form an integral part of a memory chip. Various blocks on a memory chip require uninterrupted power supply that are independent of the load conditions. The program, erase and read operations in ...

The reduction in the device dimensions, the increasing switching activity and the high power consumption in the IC design cause large currents to flow in a Power Distribution network (PDN). The switching currents cause the ...

Power Amplifiers are undoubtedly one of the most important blocks in any transmitter system. Long range communication requires a massive boost-up of the power to be delivered, before it can be launched in the channel. This ...

Low Dropout Regulators (LDOs) are extensively used in many applications ranging from high power system to the portable application like mobile phones, PDAs and notebooks.
These portable applications demand high power ...

Baluns are ubiquitous element in numerous applications such as RF/Microwave components and systems, TV receivers, and modern era telecommunication networks. These are primarily used with push-pull amplifiers, balanced ...
